johnhelmer | “War is war, whether you want to use terms like hybrid war or proxy war. It means destroying the enemy’s capacity to make war. Shutting off the power in the rump Ukrainian state will do just that to the Ukrainians. If they then start to flee for refuge to Poland and Germany, this will be a disaster unparalleled in recent European history. Just the attendant collapse in telecommunications will make the place a madhouse. You can well imagine the rest. Already there are queues for water in Nikolaev, and who knows where else. How does queueing for water, if there is any, in temperatures of minus-20C to minus-40C sound? This won’t be like the blackouts from US sanctions and attacks in Cuba or Venezuela – there they didn’t have to worry about freezing to death, the pipes bursting, or irreparable damage being done to billions of dollars’ worth of pumping, electrical, and other equipment due to freezing.”
“How many people realize that a sulphur hexafluoride (SF6) circuit breaker, commonly used in electrical substations, requires an electric heating blanket to be functional in sub-zero weather? Most westerners don’t. They are common in high voltage substations which ultimately feed the grid lines with power. In the Ukrainian case, I suspect there is a mixture of those and older style oil circuit breakers (OCB), along with oil-filled large power transformers (LPT), which are essential to electrical distribution. And guess where most of the oil comes from to fill these devices?”
“I suspect that most of Zelensky’s officials and officials in the supporting EU governments have persuaded themselves with their own propaganda. They aren’t daring to think through these questions, any more than they care to understand that the housing of the pumps delivering their water and treating their sewage will freeze and split apart if they are not heated via electrical means. Even if the gas is on — and it won’t be — electricity is needed to ignite, then control, furnaces. How many of these officials understand the long lead times, compounded by manufacturing shutdowns due to high energy costs, which you must have to replace and restore everything?”
“Who then will ‘stand with Ukraine’ when the gas and electricity rationing and unpayable consumer bills roll over the Ukrainian border and into Poland, Germany, France, and the UK, as they are already doing?”
“The Russians have been hitting the Ukrainian electrical distribution system for months now. As we know, they started with the rail traction power yards which are largely branches of the wider electric grid. Now they have moved to the substations and so-called ‘thermal power’ plants, hitting them in what seems to be pellmell fashion. I expect that the Russians are gathering intelligence now on repair times, re-equipment availability, deliveries, repair crew composition and coordination.”
“So let’s imagine this. Winter arrives. The power is cut in Kharkov, Dniepropetrovsk, Pavlovsk, Nikolaev etc. and due to the unavailability of spares, repair crews, respite from attack, or all three, the outlook for the power outage is indefinite. What do people do? They migrate to where there is power, running water, heat etc… For millions this means west. So off they go. And when enough of them get there, bam! the power goes off there too.”
Reading the grid maps of the Ukraine, the source says “it is obvious that the real vulnerability, in my estimation, lies in the approximately 88 substations for 330 kV distribution and 33 substations for 220 kV distribution. Note the nodes or junctions. Those are substations connecting the distribution lines which crisscross the Ukraine. These substations contain large power transformers, switchgear, DCS equipment [Distributed Control System] and other power quality and control equipment, spares etc. Widespread coordinated strikes on these substations will quickly overwhelm the Ukrainian ability to effect repairs and re-balance the loads on the generation stations. This will create a cascade effect whereby overloaded power plants, and distribution gear will ‘trip out’ over wide swathes of the country – if the protection between the Ukrainian and EU grids does not operate in time, or there is wild voltage/frequency oscillations there could be large interruptions in the EU countries being fed from Ukrainian sources.”
“Any repair efforts will also be severely hampered, if not crippled, if utility yards where spare cables and other gear, as well as vehicles (bucket and line trucks, cranes etc.) are stored and parked are struck. Personnel losses among the finite number of utility crew members due to follow-up attacks and the inevitable mishaps that come with interacting with damaged or compromised high voltage electrical equipment, will quickly mount. If the attacks are launched during the hard winter months, the impact will be exponential, increasingly unmanageable and catastrophic as the hours go by.”
